Hello, I am wondering if it is possible to have multiple build systems for a file type with only one of those being automatic?

Reason:I have jslint for javascript files. I'd like that to be the automatic build system for source.jsI have just added the YUICompressor as a build system. Now that is the automatic build for source.js. I'd like this one to be run only if I do so manually.

Actually this works if I just remove the selector for the the YUI Compressor build system. Now it only runs when manually selected. Now the question is "Is there a way to have multiple build systems for a given selector and toggle/step through them with some key combination?
